Pictures will be on alt.binaries. pictures.radio Have large diode. It has a
seperate small terminial on one side. Also shows a diode marking. Printing
as follows. DELCO RADIO 6909 (diode mark) 632670. Also stamped A3634 and
this is also etched on heatsink. I looked in all of solid state reference
books I have and Googled every way I could think of. It checks as a diode. I
also checked as a triac (no results). checked as SCR (no results) ??

A diode has 2 connections, SCRs and triacs have 3 so it should be easy to tell
those apart !

If it's from Delco days I'd suspect a Germanium diode.
